Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as "solar panels". Almost all commercial PV cells consist of crystalline silicon, with a market share of 95%. Cadmium telluride thin-film solar cells account for the remainder.
In a PV array, the solar cell is regarded as the key component . Semiconductor materials are used to design the solar cells, which use the PV effect to transform solar energy into electrical energy [46, 47]. To perform its duty satisfactorily, it needs to have the maximum PCE feasible .
Solar cells can be made of a single layer of light-absorbing material (single-junction) or use multiple physical configurations (multi-junctions) to take advantage of various absorption and charge separation mechanisms. Solar cells can be classified into first, second and third generation cells.
Light shining on the solar cell produces both a current and a voltage to generate electric power. This process requires firstly, a material in which the absorption of light raises an electron to a higher energy state, and secondly, the movement of this higher energy electron from the solar cell into an external circuit.
These two structures can be further divided into two categories: mesoscopic and planar structures. The mesoscopic structure incorporates a mesoporous layer whereas the planar structure consists of all planar layers. Perovskite solar cells without electron and hole-transporting layers have also been tested.
